Abstract

An uninterruptible power supply includes a backup input line isolation switch (103) and a control circuit (151) which, during operation of the reserve energy source portion (113,115) of the power supply in supplying power to the output (118,119), provides mechanical isolation between the primary energy source connected to the input line and the secondary energy source (113) upon detection of a failure of an electronic isolation switch (116) normally providing isolation between the input line and the secondary energy source or an output of the power supply.
